How To Mic A Keyboard Amplifier?

Can You Plug A Mic Into A Keyboard Amplifier?

The answer to this question depends on the keyboard amplifier you have and whether it comes equipped with XLR microphone input. If it does not feature an XLR microphone input, a great alternative is to place a mic onto the amplifier.

How To Plug A Mic Into A Keyboard Amplifier?

In trying to plug a mic into a keyboard amp, the first thing you must do is inspect your keyboard amplifier if it features an XLR microphone input. This will allow you to determine whether it can support the use of a microphone. 

Then, prepare a standard XLR cable and hook it up with your microphone and keyboard. For instance, if the keyboard you own has a separate line output for the left and right channels, you would be needing two mono jack cables.

How To Mic An Amplifier?

In microphoning an amplifier, the first you must do is set the ideal tone you desire on your amplifier. Then select the appropriate microphone for you; any dynamic mics are highly recommended. Place the microphone close to the amplifier speakers and use a mic stand or holder. It’s critical to remember that the position of the microphone has a significant impact on the sound you generate. When placing a microphone on an amplifier speaker, keep the following in mind:

  • Placing the microphone near the amplifier’s speakers will increase bass frequencies
  • Placing the microphone away from the speaker would result in a reduced overall bass response. 
  • Placing the microphone closer to the edge of the speakers sideways would reduce midrange and upper-mid frequencies.
  • Placing the microphone towards the center of the speaker would emphasize midrange frequencies. 
  • Angling the microphone towards a 45-degree angle can help control harsh high frequencies.

Note that this rule does not apply to omnidirectional microphones since they pick up sounds with equal gains from all sides of the microphone, although they are nonetheless ineffective for close-miking an amplifier. A great way to tell whether or not the position of the microphone is perfect is by doing some practice runs before performing or recording. 

What Are The Advantages Of Using Dynamic Microphones?

Dynamic microphones work well for miking an amplifier because it has omnidirectional properties. One of the main reasons why it is perfect for miking amplifiers is because it can handle high-pressure levels as well as withstand high volumes. This is because it has a rugged design making it almost 100% mechanical. 

Another advantage dynamic microphones have that makes them ideal for miking amplifiers is that they can color sounds in the range of 5 to 10 kilohertz which additionally contributes to the clarity, presence, and understandability of many vocal instruments. Despite all those benefits, dynamic microphones remain affordable and cheap costing an average of less than a hundred dollars.

What Is A Good Technique To Get The Best Microphone Position For The Best Sound?

A technique done by performers or recorders when miking an amplifier is by placing four microphones on different areas of the speaker located in the center, near center, near edge, and edge, and recording a short part of the piece you are playing. 

In terms of distance to the speakers, do the same method but this time with the microphones located very close, close, far, and quite far away from the speaker and recording again a short part of the piece you are playing. 

Lastly, listen to all recordings you have from the four different microphones and determine the best microphone position that compliments your performance. Once done, place the microphone at the corresponding position and distance on the amplifier’s speaker.
